[0 all whom it may concern i V 2 Be it known that I, JoH-N VV. ALL E, a subject of the IIingof Great Britain, residr ing at Cartiervillfe, in the Province of Quebec and Dominion 1 ed new and useful Improvements in Door- Latches, of which the following is a specification.

This invention relates to securing devices for doors and the like, and has for its object the provision of a very efficient latch b means of which adoor may be held close d' and the construction. of which is] such the door may be opened fromeither side with the utmost ease. Q

important object is. the provision of a latch of'this character in which the parts are so constructed and arranged as to be well balanced so as to facilitate the operation of the latch, the parts beingfurthermore well fitting and neatly assembled whereby the minimum effort will be re quired in actuating the latch, while at the same time the latch will be eflicient in operation.

An additional object is the provision of a latch of this character which will be simple and inexpensive in manufacture, and

installation, highly efficient in use, durable in service, and a general improvement in the art. v

With the above and other objects and advantages in view, the invention consists in details of construction to behereinafter more fully described and claimed and illustrated in the accompanying drawing, in

which- Figure l is an elevation showing vice upon one side of a door, 7

F 2 is an elevation looking at the other side of the door, Fig. 3 is a cross sectional view on the line 3-3 of Fig. 1, I

my do Fig. 4: is a cross sectional view on the line 1-4 of Fig. 1,

Fig. 5 is a cross sectional view on the line 5 -5 of Fig. 1, and a Fig. 6 is a horizontal longitudinal sectional view on the line 6-6 of Fig. 1.

ei'erring more particularly to the drawing, the letter A designates a'portion of a door and B designates a portion of the stationary jamb or the like.

In carrying out my invention I provide upon the janib B a keeper formed as a plate 10 secure-:1 upon the jamb by suitable screws Specification; of Letters. Ifatent.

of Canada, have invent-- ends upon a door. .One end of the Patented Nov. 30, 1920. 3 ,415. 7

or the like and having. a portion of its mate rial stamped out to provide a cup-like saddle 1 1 having its open edge directed up wardly. Disposed for movement over the face of the door A is a long latch bar 12 which is provided with a counter-balancing weight l3at one end, which is adapted to have its other end engaged within the keeper saddle 11, which is pivoted intermediate its stud or the like l4 extending outwardly from a plate 15 mounted, upon the door. At a point somewhat removed from free edge ofthe door A I provide a guide bracket inth e nature of a plate 16 secured upon the door and transversely slit, as 'shown, to provide tongues 17 within which are engagedthe endear a loop-like guide 18 engaging over and extending beyond the edges of the latch bar 12.

Also mounted upon the latch bar 12 at the guide structure just described, is a handle 19 which has its central portion offset from the door and conveniently shaped for comfortable engagement within the hand of an operator. Within its ends the handle is enlarged, as shown at 20, and is provided with slits or slots 21 for the passage of the latch bar 12, it being'noted that the latch bar 12 adjacent one end of the handle is slightly widened, as shown.

Disposed upon the opposite side of the door is a handle 22 which has its central portion offset and curved to be comfortable and which has end portions secured upon the handle member 22 is enlarged into a relatively large plate 23 which is providedwith a rectangular opening 24 through which and through a corresponding opening in the door extends a lever 25 which has its lower end provided with a thumb engaging portion 26. This thumb engaging portion of this latch lever is disposed at the side'of the door provided with the handle 22 and the. other end of this lever 25 extends through the door and is provided with a hook 27 upon which is engaged a link or the like 28 which has its terminal portion engaging within a suitable hole 29 in the end 30 of the handle '19 disposed adjacent the free edge of-the door.

Assuming that an operator approaches a door from its inside, in order to open the door it is merely necessary that he grasp the handle 22 and press upon the thumb member 26, whereupon the latch bar 12 will be swung upon its pivot 14-to disengage its I end from the keeper saddle 11. The operstudyof the drawing, it will be apparent" that I have thus provided anextremely simple latch mechanism which may be Very quickly and easily operated and which will be highly efiicient in use and not likely'to get.

out of order. 7 v p "While I have shown. and described the preferred embodiment of my invention, it is of course to be understood that I reserve the right to make such changes in the form,

construction, and arrangement of parts as will not depart from the sp1r1t of the invention or the scope of the subjoined claim. v

Having thus claim z- A door securing keeper-member secured upon the door jamb 1 described my I invention, I

and. having a saddle portion, a latch bar horizontally disposedand pivotally mounted 'forimovement in a vertical plane uponthej device 7 7 comprising a door, one end of said latch bar being adapted for engagement Within said keeper sad- 7 dle, a vertically extending guide bracket securedupon the door and'engaging'said latch dear for limiting movement thereof, ahandle having enlarged end portions slotted for/the passage ofsaid latch bar and having its intermediate portion offset to provide a handhold spaced from said guide bracket, a handle member secured upon the opposite side of the .door and having one end formed as an "enlarged plate provided with an opening, the door beingalso provided with an opening registering with said first named opening, an angular lever pivoted within the opening in said plate and having one end provided with a thumb engaging portion and'having its other end extendingthrough both ofsaldopeniiigs and terminating in'a hoolnand a link connected at one end with said hook and connected atjits other. end

with, the end of said first named handle adjacent the freeedge of the door.
